get方式传递多个参数给实体类或单个参数的写法

1.代码

@Data
public class Stu {

    private Integer num;

    private String name;


}

@SpringBootApplication
@RestController
@RequestMapping("/CaiNiaoController")
public class CaiNiaoController {

    /**
     * 结果:success
     * @param num
     * @return
     */
    @RequestMapping("/getNumAdd")
    public String getNumAdd(Integer num){
        if(num ==null){
            return "num参数不能为空";
        }
        num=num*5;
        return num+"";
    }

    /**
     * 结果:success
     * @param num
     * @param name
     * @return
     */
    @RequestMapping("/getNumDec")
    public String getNumDec(Integer num, @RequestParam(name ="username",required = false) String name){
        if(num ==null || name ==null){
            return "参数不能为空";
        }
        num=num/5;
        return name+" 分数:"+num;
    }

    /**
     * http://localhost:8080/CaiNiaoController/getBeanData?num=458&name=li
     * 结果:success
     * @param stu
     * @return
     */
    @RequestMapping("/getBeanData")
    public String getBeanData(Stu stu){
        return stu.getName()+" 分数:"+stu.getNum();
    }

    /**
     * http://localhost:8080/CaiNiaoController/getBeanData02?num=458&name=li
     * 结果:success
     * @param stu
     * @return
     */
    @RequestMapping("/getBeanData02")
    public String getBeanData02(@ModelAttribute Stu stu){
        return stu.getName()+" 分数:"+stu.getNum();
    }

    /**
     * http://localhost:8080/CaiNiaoController/getBeanData03?num=458&name=li
     * 结果:fail
     * @param stu
     * @return
     */
    @RequestMapping("/getBeanData03")
    public String getBeanData03(@RequestParam Stu stu){
        return stu.getName()+" 分数:"+stu.getNum();
    }

    /**
     * http://localhost:8080/CaiNiaoController/getBeanData04?num=458&name=li
     * 结果:fail
     * @param stu
     * @return
     */
    @RequestMapping("/getBeanData04")
    public String getBeanData04(@RequestParam(required = false) Stu stu){
        return stu.getName()+" 分数:"+stu.getNum();
    }

}

写法和访问的url以及访问的结果都在上图
